Galaxy Power Spectrum in General Relativity
Nastassia Grimm, Fulvio Scaccabarozzi, Jaiyul Yoo +2
We present the galaxy power spectrum in general relativity. Using a novel approach, we derive the galaxy power spectrum taking into account all the relativistic effects in observat…

Non-linear general relativistic effects in the observed redshift
Giuseppe Fanizza, Jaiyul Yoo, Sang Gyu Biern
We present the second-order expression for the observed redshift, accounting for all the relativistic effects from the light propagation and from the frame change at the observer a…

Dark energy and non-linear power spectrum
Sang Gyu Biern, Jinn-Ouk Gong
We investigate the effects of homogeneous general dark energy on the non-linear matter perturbation in fully general relativistic context. The equation for the density contrast con…
